[7p-C24-10] Evidence of the Dissipative Structure during the Long Aging of an Ultralow-Expansion Glass

〇Hiroshi Kobayashi1 (1.AIST Kansai)

Keywords:glass, aging, dissipative structure

We measured for 1300 days the aging of an ultralow-expansion glass. The glass aging is composed of an exponential clasical structural relaxation and a linear spontaneous structural relaxation which holds for a long time.
